SDN & OpenFlow

OpenFlow

Traditional networking is made up of a control plane, and data plane where the control and data planes are combined each into the network elements making up the network. This creates a limitations, because the control plane, and data plane normally resides in the individual routers and switches. Any changes in the network topology (ie: links or routing/switching devices going up/down) will have to be communicated to the other network elements. This causes a propagation delay that gets longer as the network grows.

Software Defined Networking vs Traditional Networking

Software-Defined--Networking

Traditional Networking is made up of a control plane, and data plane where the control and data planes are combined each into the network elements making up the network. This creates a limitations, because the control plane, and data plane normally resides in the individual routers and switches. Any changes in the network topology (ie: links or routing/switching devices going up/down) will have to be communicated to the other network elements. This causes a propagation delay that gets longer as the network grows.  A new set of networks known as programmable networks have emerged as a solution to this problem.
